Background High-density microarray patch (HD-MAP) vaccines may increase vaccine acceptance and use.We aimed to ascertain whether professional immunizers (PIs) and other healthcare workers (HCWs) in Australia, a High-Income Country (HIC), found the HD-MAP applicator usable and acceptable for vaccine delivery.Methods This feasibility study recruited PIs and HCWs to administer/receive simulated HD-MAP administration, including via self-administration.We assessed usability against essential and desirable criteria.Participants completed a survey, rating their agreement to statements about HD-MAP administration.

A subset also participated in Twin XL Mattress an interview or focus group.Survey data were analyzed using descriptive statistics, and interviews were transcribed and subject to thematic analysis.Results We recruited 61 participants: 23 PIs and 38 HCWs.Findings indicated high usability and acceptability of HD-MAP use across both groups by a healthcare professional or trained user and for self-administration with safety measures in place.Most administrations met essential criteria, but PIs, on average, applied the HD-MAP for slightly less time than the required 10-seconds, which the HCWs achieved.

PIs perceived safety concerns about home administration but found layperson self-administration acceptable in an emergency, pandemic, and rural or remote settings.Conclusions Participants found HD-MAP administration usable and acceptable.Usability and acceptability are likely to be improved through end-user Collections education and training.
